4. An insulating spherical shell of radius inner radius A and outer radius B, has a non-
uniform charge density given by p(r)= ar³ where a is a constant. Concentric with
this spherical shell is an insulating spherical shell with inner radius B, outer radius
C, and a uniform charge density such that the electric field strength is zero for r > c.
a. What is the total charge on the inner spherical shell?
b.
What is the charge density in the outer spherical shell?
c. What is the electric field everywhere (r < A, A <r< B, and B <r<C?
